-----------------------------------
Summary: Fix & extend x509_extension event
Key: BIT-1120
URL: https://bro-tracker.atlassian.net/browse/BIT-1120
Project: Bro Issue Tracker
Issue Type: Problem
Components: Bro
Affects Versions: 2.2, git/master
Reporter: Bernhard Amann
Fix For: 2.3
Please merge topic/bernhard/fix-x509-extension.
This branch fixes and extends the x509_extension event, which was never called
in the previous implementation. The event now parses the extension into a bro
data structure. If supports printing it, it is converted into the openssl ascii
output, otherwise a raw hex-dump is output.
New event syntax:
event x509_extension(c: connection, is_orig: bool, cert:X509, extension:
X509_extension_info)
Example output for extension:
[name=X509v3 Extended Key Usage,
short_name=extendedKeyUsage,
oid=2.5.29.37,
critical=F,
value=TLS Web Server Authentication, TLS Web Client Authentication]
[name=X509v3 Certificate Policies,
short_name=certificatePolicies,
oid=2.5.29.32,
critical=F,
value=Policy: 1.3.6.1.4.1.6449.1.2.1.3.4^J CPS:
